Original description. — Towards the end of May last (1850) in 

 searching for the larvffi of Psyche nitidella, which abound in the neigh- 

 bourhood of Camberwell, I observed on some old palings a quantity of 

 oval, green larva-cases, resembling small specimens of Turbo littoralis ; 

 they were in constant motion, which called my attention to them, and 

 I secured several dozens in the hope of ascertaining the species to 

 which they belonged. In this I was disappointed, for the whole of them 

 changed about the middle of July and proved to be the females of a 

 new species (at least to us) of Talaeporia, closely resembling, but not 

 identical with, T. tabidella, and figured by Bruand in the Ann. de la 

 Soc. Ent. de France, 2nd ser., ii., pi. vi., fig. e, under the name of 

 Solenobia clathrella. The insect so closely resembles the figs. 17, 18, 

 19, in pi. xv., vol. hi., of Beaumur, that I believe it to be identical, 

 and propose to call it T. ferchaultella, after one of that celebrated 

 writer's names ; it is, however, somewhat more attenuated posteriorly 

 than in the figures, but that form might have escaped notice at the 

 time they were executed. In colour, the living insect was dull 

 ochreous, annulated with brown ; but in the dried specimens wholly 

 of the latter colour, and the length of the largest specimen is scarcely 

 two lines (Stephens, Zoologist, viii., p. cix). 



Imago. — The female (no male is known), beyond being smaller, 

 looks very like that of L. lapidella ; the colouring is perhaps rather 

 blacker. The emargination of the mesothoracic plate is greater than 

 in Is. lapidella, whilst that of the metathoracic is very great, so that 

 it almost resembles that of the 1st abdominal ; it differs from it by 

 having a dark chitinous portion centrally that is little more than a 

 dorsal line, and the border is a little wider and darker ; the 1st abdo- 

 minal has a narroAV dark chitinous anterior border, little more than a 

 line, prolonged at the spiracular region as a curved line to the pos- 

 terior margin of segment ; the 2nd- 6th abdominal segments have a 

 dark plate on either side not very different on the several segments but 

 smallest on the 5th, a larger one on the 7th, followed by the anal
